BACKGROUND OF INVENTION

[0004] In the past the column shaft had to be lifted in a vertical direction in the location of its final position. While raised, legs or blocks (usually of wood) had to be placed or installed under and to the column. This system provided no tie-down strength, but has been used commonly in column installation.

BRIEF SUMMARY OF INVENTION

[0005] The column jack invention lifts the column shaft into its final position with mechanical advantages such as levers and wedges (threads). It reduces the effort and provides a more simple method of installation. The base of the column jack is bolted or screwed to the substrate and to the column providing tie-down strength. It's main body is simply turned to lift the column.

DETAILED DESCRIPTION OF THE INVENTION

[0035] The invention to be patented has a basic design, though the one that was produced is described below possible alternates will be mentioned in a final paragraph. The invention is made up of three basic parts. They will be described in the following paragraphs, along with the pieces of each part and how the pieces relate to one another. There will also be a paragraph describing how the parts relate to one another and how they are assembled.

[0036] The first is the column jack main body part. It is made of square tube steel, a nut and a washer. The square tube steel is standard industry one inch,—gauge. Cut to five inch long pieces. The inside diameter is about {fraction (13/16)} of an inch. The nut is a standard 5 grade ½ inch course thread. The nut is placed a quarter of an inch into the inside of the square tube steel, leaving {fraction (3/16)} of an inch exposed. It is placed such that the threaded hole runs the same direction as the length, centered. It is tack welded at the four places the nut contacts the tube steel.

[0037] The second is the column jack base part. It includes two pieces. One is a standard ½ inch course threaded rod six inches long. The other is a base plate made of a standard one inch—gauge strap steel cut to a three inch length. This piece has three punched holes centered along the centerline that runs the length of the metal strap. There is one in the middle that has diameter of a ½ an inch (positioned at 1.5 inches from either side, centered). The other two holes are positioned ⅞ of an inch on either side from the center point of the afore mentioned hole. They are {fraction (7/16)} in diameter. The rod is welded to the base perpendicularly. The rod is positioned such that it passes partially through the base plate and the end of the rod doesn't clear the opposite side of the base plate. The rod is welded to the base plate in the small abscess formed by the hole and the threaded rod. If the weld exceeds flushness with the back of the base plate it is removed with an angle grinder.

[0038] The third is the column attachment. It includes an “L” bracket, two washers, and a {fraction (7/16)} inch bolt. The “L” bracket is made of 2 inch wide strap steel,—gauge. It is cut at three inches and bent in the middle at 90 degrees length wise. It has three punched holes, one with a {fraction (7/16)} inch diameter, and two quarter inch. The larger hole is centered in both directions on one of the two flat areas (the holes' location is 1 inch on the two inch dimension and three quarters of an inch between the cut edge and the 90 degree angle). The other two holes are on the flat area (not on the same flat area as the {fraction (7/16)} inch hole). The quarter inch holes are centered between the other cut edge and the 90 degree angle. Each hole is ½ an inch in from both of the finished edges. The {fraction (7/16)} inch bolt is welded with it's threaded tip in the {fraction (7/16)} inch hole in the “L” bracket. The washers are also standard industry with the inside diameter of {fraction (7/16)} of an inch and an outside diameter of one inch. They are—gauge. The bolt go through the washers before the washer is welded to the bracket. The washers move freely between the bracket and the blot's head.

[0039] The pieces are put together in the following way. The column jack base part's threaded rod is threaded into the nut on the column jack main body part. It is threaded in from the face that the nut is welded to. On the opposite end the column attachment part is attached in the following way. The bolt head is inserted in the tube steel. The washer furthest from the bracket is welded to the opening in the tube steel (or column jack main body). The other washer should still move freely between the bracket and the welded washer. The bolt and “L” bracket assembly should have some play because the only piece in the column attachment assembly that is attached to the column jack part is the washer mentioned before, which was welded.

[0040] This invention can be altered both in size and can be made with varying dimensions. The important aspects are that the piece that connects to the column is free spinning from the main body section, and that the main body section is threaded female for an opposing male threaded piece that can attach to the substrate. The nut mentioned in the above paragraphs doesn't need to be a nut, it only needs to be a threaded attachment to the main body. The washer welded to the main body simple needs to be a hole that allows the column attachment to spin freely on the same axis as the length of the column jack main body. This also means that the bolt used in the column attachment assembly doesn't need to be a bolt but simply a piece with a middle section that is narrow enough to fit through the hole at the top of the column jack main body an end that is larger than the hole but that can spin freely inside of the main body and the other end can be attached to the column attachment. The “L” bracket only needs the properties that will allow it to attach to the column and spin freely of the column main body, and it doesn't need to be an “L” bracket necessarily.
